4434NASA Learning Objects: PLANE MATHhttp://www.merlot.org/merlot/viewMaterial.htm?id=239800
״This NASA video segment briefly explores how the development of the Hyper-X experimental airplane will impact the future of flight. Viewers learn that if commercial airlines incorporate Hyper-X technology into their aircraft, people will be able to travel across the United States in about 30 minutes. The remainder of the segment explores the Plane Math interactive Web site. The Plane Math site has eight training departments with information about aeronautical principles. Besides many interactive learning tools, Plane Math includes geometry- and algebra-related concepts. Students simulate designing an aircraft for a client and testing the design in a virtual wind tunnel. "NASA Learning Objects: Pop Rocketshttp://www.merlot.org/merlot/viewMaterial.htm?id=220470
This is a primary to middle school activity that is hands on building a rocket. Call the parent helpers before you try this one!NASA Learning Objects: Schoolyard Solar Systemhttp://www.merlot.org/merlot/viewMaterial.htm?id=238726
The vastness of the solar system offers a unique lesson in large numbers and in scale. THE SCHOOLYARD SOLAR SYSTEM was developed to demonstrate the solar system to scale; to show the relationship between units of thousands, millions, and billions; and to accomplish these goals with student involvement that will re-enforce the lessons. NASA Learning Objects: The Gas Labhttp://www.merlot.org/merlot/viewMaterial.htm?id=220237
This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the four primary properties and study the nature of the relationship between the other two by varying one and observing the variation of the other. The variations are demonstrated using computer graphics in the animated gas lab.
